G. Vancraeynest et al., THE NE-19(P,GAMMA)NA-20 ASTROPHYSICAL REACTION-RATE DETERMINED FROM MEASUREMENTS WITH A RADIOACTIVE BEAM, Nuclear physics. A, 616(1-2), 1997, pp. 107-114
The Ne-19(p,gamma)Na-20 as well as the Ne-19(d,n)Na-20 reaction have b
een studied in inverse kinematics using Ne-19 radioactive beams. Upper
and lower limits for the Ne-19(p,gamma)Na-20 astrophysical reaction r
ate have been deduced, for the first time on the basis of direct exper
imental data. It is concluded that the transition from the hot-CNO cyc
le to the rp-process in explosive hydrogen burning is most likely gove
rned by the preceeding O-15(alpha,gamma)Ne-19 reaction.
